The pool is 50m long, 10m wide and 2m deep. The pool is completely filled with water. With what force does the water press on the bottom of the pool?

l = 50 m.
a = 10 m.
h = 2 m.
ρ = 1000 kg / m ^ 3.
g = 9.8 m / s ^ 2.
F -?
Water presses on the bottom of the pool with gravity F, which is determined by the formula: F = m * g, where m is the mass of water in the pool, g is the acceleration of gravity.
Let’s find the mass of water m in the pool by the formula: m = ρ * V, where ρ is the density of the water, V is the volume of water in the pool.
The pool has the shape of a rectangular parallelepiped, the volume of which is found by the formula: V = l * a * h.
F = ρ * l * a * h * g.
F = 1000 kg / m ^ 3 * 50 m * 10 m * 2 m * 9.8 m / s ^ 2 = 9800000 N.
Answer: water presses on the bottom of the pool with a force of F = 9800000 N.
